1Jupiter and Saturn have solid surfaces beneath their massive atmospheres.
- AVerdadero
- BFalso
2Jupiter and Saturn have cores of molten rock and iron.
- AVerdadero
- BFalso
3Which planet is the largest in the Solar System?
- AJupiter
- BSaturn
- CNeptune
- DUranus
4What is Saturn known for?
- AA "Great Red Spot" which is a massive storm.
- BSpectacular Rings of made of ice and some dust.
- CIt's many moons, having 63 confirmed moons.
- DThick bands of alternating darker and light gases.
5What is Jupiter known for? (Check all that apply)
- AAlternating parallel bands of dark and light clouds.
- BA "Great Red Spot" which is a massive storm.
- CIts many moons, numbering around 63 total moons.
- DLarge and spectacular rings of ice and dust that orbit around the planet.
6Astronomers think that the material at the very center of Jupiter is composed mainly of:
- AHydrogen
- BUranium
- CWater
- DHelium
- EMolten rock and iron
7The low average density of Saturn suggests that:
- ASaturn is hollow.
- BSaturn's gravitational attraction has compressed its core into a rare form of iron.
- CSaturn contains large quantities of light elements, such as hydrogen and helium.
- DSaturn is very hot.
- EVolcanic eruptions have ejected all the iron that was originally Saturn's core.
8How does Saturn compare to Jupiter?
- AIt is smaller in diameter, with less mass.
- BIt is smaller in diameter, with more mass.
- CIt is larger in diameter, with less mass.
- DIt is larger in diameter, with more mass.
9The amount of infrared energy emitted by Jupiter is about twice as great as the amount of sunlight that planet absorbs. What is the significance of this discrepancy?
- AIt implies that the planet is cooler than it should be.
- BIt implies that there are significant energy sources within Jupiter.
- CIt implies that the Sun was once much dimmer than it is now.
- DIt implies that the rotation of Jupiter must be slowing down.
10What causes Jupiter and Saturn to have substantially larger radii <-(plural of radius) at their equators than at their poles?
- AThey spin so fast that inertia causes the equator to bulge.
- BHigh-energy storms near the equator cause the atmosphere to expand there.
- CIntense magnetic fields pull the atmosphere in at the poles.
- DThese icy planets accumulated most of their planetesimals along their equators as they formed.
11Jupiter and Saturn outweigh the combined total of everything else in the Solar System that is smaller than them.
- AVerdadero
- BFalso
12Why is Saturn's coloration less distinctive than Jupiter's?
- ASaturn has a high-altitude haze of frozen ammonia particles, causing it to have a duller coloration.
- BSaturn is far hotter than Jupiter, causing it to "boil off" most of the elements that make Jupiter colorful.
- CSaturn has strong storms that mix the elements in its atmosphere giving it a "muddy" appearance.
13The Gas Giants are made of mostly Hydrogen and Helium, but with cores of molten rock and iron much more massive than the Earth.
- AVerdadero
- BFalso
14Jupiter and Saturn's high pressures causes hydrogen to be compressed to a metallic, electrically conducting state.
- AVerdadero
- BFalso
15Jupiter and Saturn rotate very rapidly, causing:
- AHigh-speed "Jet Streams" that move in opposite directions.
- BLayers of the outer atmosphere to be thrown into space.
- CThe planets to "wobble" on their axis.
- DA mixing of clouds, making the appearance of the surface to seem "muddy".
16Jupiter and Saturn have strong magnetic fields, probably produced by electric currents in the metallic hydrogen.
- AVerdadero
- BFalso
17The magnetic fields of Jupiter and Saturn funnel electrically charged particles towards the magnetic poles, creating auroras (similar to our Northern Lights).
- AVerdadero
- BFalso
18What is the "Great Red Spot"?
- AIt is a storm larger than the Earth that has persisted for hundreds of years on Jupiter. It is thought to be driven by rapid opposing flows of belts and zones (Jet Streams) in Jupiter's atmosphere.
- BIt is a giant aurora that takes place once every hundred years on Jupiter's poles, noted for its beautiful red colors.
- CIt is the nickname for one of Jupiter's many moons. The "Great Red Spot" orbits around Jupiter while rotating very quickly, making it seem like a vortex on Jupiter's surface.
- DIt is a deposit of organic molecules (molecules made chiefly of carbon) that may indicate past life on Jupiter.
